When using the website, puzzles must be solved in one session. If the computer goes to sleep, the window disappears and I'm left with the coffee cup picture with a red exclamation mark over it. Also, the grid is horrible to look at on my MacBook Pro with large, dark question marks on the empty grid. Everything looks and works perfectly on OS 10.4 - PowerBook and PowerMac. Anyone else using Snow Leopard?

I'm using Snow Leopard but I'm kinda having the opposite problem. I finish a puzzle and try to go on to the next puzzle but the puzzle I just finished won't let me exit or close. It doesn't happen all the time but I've had to shut down my internet browser completely and start it again just to close an old puzzle so I could start a new one.

HiI am using Lion, so it is a bit different. One of possible solutions is to install Open JDK instead of Sun Java preinstalled with Mac OS. Here is a list of all possible builds of OpenJDK for Mac http://code.google.com/p/openjdk-osx-build/ , just choose latest stable version for your OS.

Reading these posts, I wonder why the Java applet was working just fine for me until about 3 days ago. I am running Snow Leopard on my Intel Mac, and I wasn't having any problem with the new version since it was first presented.

Suddenly nothing will work for me but the old applet. Do I need a new OS?
